Naturforsch. 34b, 700-705 (1979); received January 9, 1979 Metallocycles, Organo-Iridium Compounds, Oxidative Addition The reaction between (h5-cyclopentadienyl)carbonyl(triphenylphosphine)iridium and bis(pentafluorophenyl)acetylene has been investigated in detail. As in ...
متن کاملCycloaurated triphenylphosphine-sulfide and -selenide.
The first examples of cycloaurated phosphine sulfides and triphenylphosphine selenide have been synthesised; these complexes are fairly rare examples of gold(iii) complexes with potentially reducing sulfur- and selenium-donor ligands. The cycloaurated complex (AuCl(2)(2-C(6)H(4)P(S)Ph(2)) was synthesised in good yield by transmetallation of the organomercury precursor Hg(2-C(6)H(4)P(S)Ph(2))(2)...
متن کاملDirect evidence of a multicentre halogen bond: unexpected contraction of the P-XXX-P fragment in triphenylphosphine dihalides.
Triphenylhalophosphonium halides, Ph(3)PX(2), form crystals comprising bridged linear cations [Ph(3)P-X-X-X-PPh(3)](+) where the X(3) bridge is shortened from 6.56 Å in Cl-Cl-Cl to 6.37 Å in the Br-Br-Br system. It is proposed that this structure is stabilised by five-centre/six-electron (5c-6e) hypervalent interactions.

TPP proceeds by a one-electron transfer to form the anion radical which undergoes cleavage of a phenyl group. The electrochemical reduction of triphenylphosphine (TPP) and triphenylphosphine oxide (TPPO) has The reduction of everal recent papers have been concerned with the S polarography of triphenylp...
متن کاملUtility of Triphenylphosphine Dihalides in Organic Reactions : Esterification Using Triphenylphosphine Dibromide as the Dehydrating Agent
A new esterification method was investigated using triphenylphosphz'ne dibromide as a dehydrating agent. This investigation has established that the method is useful when the acid is aromati~ or arylallylic. That primary and secondary alcohols esteTZfy acid satisfactorily whereas tertiary alcohols fail to react was also established in this experiment.
